Ukubunjwa kwesanti yeyona ndlela yemveli yokuphosa, yindlela yokuphosa apho isanti isetyenziswa njengeyona nto iphambili yokubumba ukulungiselela ukubumba. Isinyithi, intsimbi kunye neyona nto i-non-ferrous alloy castings inokufumaneka ngokuphosa isanti. Ngenxa yokuba izinto zokubumba ezisetyenziselwa ukuphosa isanti zixabiso eliphantsi kwaye kulula ukuzifumana, kwaye ukubunjwa kokubunjwa kulula ukwenza, kunokuhlengahlengiswa kwimveliso yesiqwenga esinye, imveliso yebhetshi kunye nobuninzi bemveliso. Kuye kube yinkqubo esisiseko kwimveliso yokuphosa ixesha elide.
Inkqubo esisiseko yenkqubo yokuphosa isanti ikakhulu ibandakanya ezi zigaba zilandelayo: ukwenza isikhunta, ukuxuba isanti, ukubumba, ukunyibilika, ukugalela, nokucoca.
1. Inqanaba lokuvelisa i-mold: Yenza iimbumba ngokweemfuno zemizobo. Ngokuqhelekileyo, iimbumba zomthi zingasetyenziselwa ukuveliswa kweqhekeza elinye, ukubumba kweplastiki kunye nokubumba kwesinyithi kunokwenziwa ukuveliswa kobuninzi, kunye neetemplates zingenziwa kwi-castings enkulu.
2. Inqanaba lokuxutywa kwesanti: Ngokweemfuno zokwenziwa kwesanti yokubumba kunye neentlobo zokubunjwa, isanti yokubumba efanelekileyo ilungiselelwe ukubumba / ukwenza i-core.
3. Inqanaba lokwenza imodeli/engundoqo: kuqukwa ukwenza imodeli (ukwenza umngxuma wokubunjwa ngesanti ebumbayo), ukwenziwa kondoqo (ukwenza imilo yangaphakathi yokubunjwa), kunye nokuhambelana nokungunda (ukubeka umbindi wesanti kumngxuma kunye nokuvala umphezulu. kunye neebhokisi zesanti ezisezantsi) . Ukubumba likhonkco eliphambili ekwakhiweni.
4. Inqanaba lokunyibilikisa: Lungiselela ukubunjwa kweekhemikhali ngokwezinto ezifunekayo zetsimbi, khetha isithando somlilo esifanelekileyo sokunyibilikisa i-alloy material, kwaye wenze ulwelo olululwelo olufanelekileyo lwesinyithi (kubandakanywa ukubunjwa okufanelekileyo kunye nobushushu obufanelekileyo).
5. Inqanaba lokugalela: tofa isinyithi esinyibilikisiweyo esifanelekileyo kwibhokisi yesanti exhotyiswe ngokungunda. Nika ingqalelo kwisantya sokuthulula xa ugalela, ukwenzela ukuba isinyithi esityhidiweyo sinokuzalisa i-cavity yonke. Inqanaba lokuthulula linobungozi, ngoko ke ingqwalasela ekhethekileyo kufuneka ihlawulwe ngokukhuselekileyo.
6. Inqanaba lokucoca: Injongo yokucoca kukususa isanti, ukugaya kunye nentsimbi engaphezulu kwi-casting, kunye nokuphucula ukubonakala kwendawo yokuphosa. Emva kokuba isinyithi esityhidiweyo siqiniswe emva kokuthululelwa, isanti ebumbayo iyasuswa, i-sprue kunye nezinye izinto ezincedisayo zisuswe, kwaye i-casting efunekayo yenziwe, kwaye ekugqibeleni iziphene zayo kunye nomgangatho jikelele zihlolwe.
Isanti yeCeramic ineenzuzo zokuchasana nokushisa okuphezulu, akukho kuphazamiseka, akukho thuli, i-spherical shape, i-air permeability ephezulu, ukusebenza kakuhle kokuzaliswa, akukho bungozi bothuli lwe-silica, njl. Kufanelekile ukuchithwa kwesanti (isanti yokubumba, isanti engundoqo), indlela ye-V yokuphosa, ukuphosa i-foam elahlekileyo (isanti yokuzalisa), i-coating (isanti ye-ceramic powder) kunye nezinye iinkqubo zokuphosa. Isetyenziswa kwiinjini zemoto kunye namalungu emoto, intsimbi enkulu, intsimbi engatyiwayo, kunye nentsimbi, ukujulwa kwe-alloy engekhoyo kunye nezinye iindawo ezisetyenziswa ngokubanzi, ezaziwa njengesanti yokuphosa eluhlaza kunye nokusingqongileyo.
